11.0.9

General

• IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
• Behavioral Change -
  When there isn't a previous active node and the user enters the grid using tab or shift + tab key:
  the first fully visible element is activated: /no scroll bar positioning is reset/changed;
  If there is a previous active node in the grid - the previously active node is reactivated without resetting the scroll positions;
  If we follow the default tab navigation and we are currently on a data cell with / rowIndex: -1, columnIndex: 6/ for example
  when we tab down to the root summaries the summary cell with visible column index 6 should be activated and scroll into the view;
  The same applies if you shift+tab to the headers header cell with visible index 6 is activated and scrolled into the view;
  If you have an active node and go to another tab and then return back the active node and the current scroll position should not be changed;
